9800A resets but does not dispense fuel – Pump.
Possible Cause
Checks
Corrective Action
No 115/230VAC feed to pump. Check if circuit breaker is off
or tripped.
Check if 115/230VAC is being
switched through circuit
breaker.
Check if 115/230VAC is
measured in the junction box.
Turn breaker on, if off.
Replace circuit breaker if
115/230VAC is not being
switched.
Correct wiring problems if
115/230VAC is not being
measured.
Defective CPU PCB.
Using a DC voltmeter,
measure between ground
(CPU PCB test point TP2) and
screw terminal #4 (blue wire
for side 1, violet wire for side
2) of the pump relay. The
voltage should be 0VDC.
If equipped with an optional
solenoid valve, measure
between screw terminals 1
and 3 of terminal block SOL1
and SOL2, using an AC
voltmeter.
Replace the CPU PCB if
+5VDC is measured between
ground and the blue or violet
wires.
NOTE: Changing the pulser
rate switches may require
replacement of your Weights
and Measures seal.
Replace the CPU PCB if
115/230VAC is not measured
between screw terminal 1 and
3.
NOTE: Changing the pulser
rate switches may require
replacement of your Weights
and Measures seal.
Defective pump relay.
Using an AC voltmeter,
measure between AC neutral
and screw terminals #1 and #2
of the pump relay.
Replace the relay if
115/230VAC is measured at
screw terminal #1 but not at
#2.
Defective optional solenoid
valve.
Solenoid valve should click
after reset.
Replace valve if click is not
heard after reset.
Defective pump motor.
Motor should turn when
115/230VAC is measured in
AC junction box.
Replace pump motor if
115/230VAC is not measured.
Out of fuel.
Check fuel level in tank.
Order fuel if tank empty.
Pump will not prime or loses
prime.
Dirty strainer.
Loose V-belt.
Air leak in suction line,
excessive lift, bypass valve
stuck on open, air separator
float stuck open, float chamber
valve open.
Remove strainer cap and
clean strainer.
If belt is loose, tighten
according to
Installation/Operation Manual
instructions.
Call qualified service
personnel if any of these
conditions exist..
